Abstract
The utility model aims to provide a headrest guide pipe positioning and anti-burn through structure which can solve the technical problem that materials cannot be stripped due to weld-through. The headrest guide pipe positioning and anti-burn through structure comprises a fixed support, a limit stopping block and a positioning pin, and is characterized in that the positioning pin consists of a precise positioning pin and an auxiliary positioning pin which is adjacently connected with the precision positioning pin; and the outer surface of the auxiliary positioning pin is a profile modeling surface which can be fitted with a headrest guide pipe.
Description
Technical field
The utility model relates to the headrest catheter positioning and the anti-burn-through structure of automotive seat.
Background technology
The weld jig of general headrest conduit is only located the headrest conduit, but in the actual production operation, usually takes place because burn, and the headrest conduit can't be dialled situation down, in the time of seriously even can damage anchor clamps.
As shown in Figure 1; Headrest catheter positioning structure is arranged in the arc welding equipment of car seat headrest pipe; It comprises the limit stop 14 between hold-down support 11, alignment pin 12, hold-down support 11 and the alignment pin 12 and is arranged on the protruding pin 13 on the alignment pin 12; Headrest catheter positioning pin adopts the steel alloy modifier treatment, and checks the inside overlap of headrest conduit with protruding pin 13.Its shortcoming is to burn the headrest conduit when arc-welding, when overlap is arranged, can't take off material, and sealing-off will be destroyed anchor clamps and part simultaneously by force.
The utility model content
The purpose of the utility model is to provide a kind of headrest catheter positioning and anti-burn-through structure, and it can solve the technical problem that can't take off material.
Headrest catheter positioning and anti-burn-through structure comprise hold-down support, limit stop and alignment pin, are characterized in that alignment pin constitutes by the fine positioning pin and in abutting connection with the assist location pin of fine positioning pin, the outer surface of assist location pin be can with the imitation profile of headrest conduit applying.
Described headrest catheter positioning reaches prevents that burn-through structure, its further characteristics are, the fine positioning pin is the alloy steel pin, and the assist location pin is a beryllium copper profiling pin.
Because aforementioned techniques scheme:
1. the finger setting of front end fine positioning is accurate, and the fine positioning axle is wear-resisting, can guarantee product precision in the production cycle; Rear end assist location pin assist location increases position stability;
2. the imitation profile of assist location pin prevents to rock, and prevents that the part dress is wrong;
3. after the imitation profile of assist location pin and product were fitted, when burn-through, the thermal conductivity of copper was splendid, and the welding liquation cools off along imitation profile, guarantees qualified products;
4. even burn-through, inside can not form overlap yet, and product and anchor clamps can adhesions, and it is convenient to take off part, does not destroy anchor clamps and product.
Description of drawings
Fig. 1 is the sketch map of existing headrest catheter positioning structure.
Fig. 2 is headrest catheter positioning of the utility model and the sketch map of preventing an embodiment of burn-through structure.
Fig. 3 is the schematic cross-sectional view of assist location pin among Fig. 2.
The specific embodiment
As shown in Figures 2 and 3; Headrest catheter positioning and anti-burn-through structure comprise hold-down support 21, limit stop 24 and alignment pin 220; Alignment pin 220 constitutes by fine positioning pin 22 and in abutting connection with the assist location pin 23 of fine positioning pin 22, and the outer surface of assist location pin 23 is the imitation profile that can fit with the headrest conduit.
Because 22 accurate positionings of fine positioning pin, the fine positioning axle is wear-resisting, can guarantee product precision in the production cycle; Assist location pin 23 assist location increase position stability;
The imitation profile of assist location pin 23 prevents to rock, and prevents that the part dress is wrong;
After the imitation profile of assist location pin 23 and product were fitted, when burn-through, the thermal conductivity of copper was splendid, and the welding liquation cools off along imitation profile, guarantees qualified products;
Even the product burn-through that assist location pin 23 is corresponding, inside can not form overlap yet, and product and anchor clamps can adhesions, take off part and make things convenient for, and do not destroy anchor clamps and product.
Claims (2)
1. the headrest catheter positioning reaches anti-burn-through structure; Comprise hold-down support, limit stop and alignment pin; It is characterized in that alignment pin constitutes by the fine positioning pin and in abutting connection with the assist location pin of fine positioning pin, the outer surface of assist location pin is the imitation profile that can fit with the headrest conduit.
2. headrest catheter positioning as claimed in claim 1 and anti-burn-through structure is characterized in that the fine positioning pin is the alloy steel pin, and the assist location pin is a beryllium copper profiling pin.
